Title:
  System slows/chugs/stutters then freezes when physical memory is low
  kswapd0

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  My laptop I have loaded with 13.10 and right off the bat I noticed
  that sometimes out of the blue the mouse would start skipping, the
  system would become unresponsive, and then completely lock up, only a
  power off would restore it. The next time I caught it and closed some
  apps right away and the system stayed alive, but following me opening
  more the behavior was reproduced. I started watching top while this
  happened and I see kswapd0 is active and my physical memory (only 2GB)
  is low prior to the system grinding to a halt. I'm operating an a
  sata3 ssd for disk and I have 2GB of swap space which was hardly
  used... bandwidth is lightning as you would expect so it's not like I
  have a slow swap space that I'm just waiting for (besides, it doesn't
  seem to ever wake up).

  ... seems to have a number of users toward the end complaining of the
  same symptoms and they were directed to file something here, however I
  didn't see any responses back indicating that it had been done, and as
  my system is fully up to date I have to assume this issue remains.

  Thanks,

  Zach
